目的：比较宫颈癌术后患者三维适形(3D-CRT)和固定野调强放射(IMRT)治疗中膀胱受照剂量的差异。方法：收治Ⅰb～Ⅱb期宫颈癌术后患者55例，28例给予3D-CRT治疗，27例给予IMRT治疗。比较两组治疗计划的剂量-体积直方图(DVH)，将膀胱作为独立危及器官进行剂量评估。结果：在 IMRT 与3D-CRT 治疗中，膀胱的 V40， V30受照剂量差异有统计学意义(P＜0.05)。结论：对于宫颈癌术后放疗患者，采用IMRT技术可以使膀胱减少照射，减轻膀胱的并发症。
목적：비교궁경암술후환자삼유괄형(3D-CRT)화고정야조강방사(IMRT)치료중방광수조제량적차이。방법：수치Ⅰb～Ⅱb기궁경암술후환자55례，28례급여3D-CRT치료，27례급여IMRT치료。비교량조치료계화적제량-체적직방도(DVH)，장방광작위독립위급기관진행제량평고。결과：재 IMRT 여3D-CRT 치료중，방광적 V40， V30수조제량차이유통계학의의(P＜0.05)。결론：대우궁경암술후방료환자，채용IMRT기술가이사방광감소조사，감경방광적병발증。
Objective:To compare the differences of bladder radiation doses in three dimensional conformal(3D-CRT) and fixed wild intensity-modulated radiotherapy(IMRT) treatment of patients after cervical cancer surgery.Methods:55 cases of Ⅰb~Ⅱb stage cervical cancer patients after surgery were selected.28 cases were given 3D-CRT treatment.27 cases were given IMRT treatment.The treatment plan dose-volume histogram(DVH) of two groups were compared.The dose was evaluated when bladder as an independent risk organ.Results:In the treatment of IMRT and 3D-CRT,V40 and V30 radiation dose of bladder had significantly different(P<0.05).Conclusion:For cervical cancer patients with postoperative radiotherapy,using IMRT technology can reduce the radiation of bladder,reduce the complications of bladder.
